Under this mode, kelp production is high, but the ropes are complex and intertwined. The main method of kelp harvesting is manual. To reduce the labor intensity and improve the harvesting efficiency of kelp, this study designs a three-body kelp harvesting ship based on the floating raft aquaculture mode. This ship can lift, transport, collect, and transfer kelp in a single operation. Apart from the manual assistance required for the release and hanging the seedling rope, all other processes are mechanically automated. The diameter and lead of the rotary-screw propulsor blade were determined through Fluent simulation tests. To verify the actual harvesting effect of the three-body kelp harvesting ship, kelp harvesting performance tests were conducted. The results showed that the working speed and efficiency of mechanized harvesting were significantly higher than manual. The mechanical harvesting efficiency was 18.75 times that of manual, and the per capita harvesting efficiency was 9.33 times that of manual. The kelp loss rate of the harvesting ship was 3.25 %, slightly higher than that of manual. This study can provide a certain reference for the mechanized harvesting of kelp in large-scale aquaculture.</div></div>","PeriodicalId":8120,"journal":{"name":"Aquacultural Engineering","volume":"110 ","pages":"Article 102545"},"PeriodicalIF":3.6,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143844475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous methods based on static image analysis are constrained by occlusion and limited generalization. Dynamic counting methods based on multi-object tracking (MOT) hold promise in addressing these challenges, but they still have counting accuracy and speed limitations due to algorithmic constraints. To address these limitations, we propose a dynamic <em>Micropterus salmoides</em> (largemouth bass) fry tracking and counting method tailored for densely occluded environments. Specifically, we employed the anchor-free You Only Look Once version 8 (YOLOv8) architecture, replacing its backbone with the lightweight and truncating the detection head at the highest level of YOLOv8 to enhance detection accuracy and efficiency. Furthermore, we adopted the Tracking-By-Detection architecture, optimized Kalman filtering's parameter updating for motion prediction, and enhanced the data association algorithm. This approach facilitates rapid and stable fry trajectory prediction and tracking while dramatically reducing identification switches, improving counting accuracy. Additionally, we constructed a dedicated dataset for fry tracking and counting, classifying videos by the density of fry in a single frame and the total number of fry across all frames. Experiment results have demonstrated that our method achieves up to 97 % counting accuracy in densely occluded scenarios (up to 62 fry per frame) and 100 % counting accuracy in scenarios with minimal occlusion (up to 19 fry per frame). Moreover, it can run at 19 frames per second on edge devices, thereby meeting the requisite speed and accuracy criteria.</div></div>","PeriodicalId":8120,"journal":{"name":"Aquacultural Engineering","volume":"110 ","pages":"Article 102546"},"PeriodicalIF":3.6,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143848483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aerobic digestion of fish sludge was performed using biofertilizer containing phosphate-solubilizing bacteria (PSB) (<em>Pseudomonas putida</em> strain P13 and <em>Pantoea agglomerans</em> strain P5; 10⁷ CFU/mL for each bacterium) at a levels of 0.1 % for 14 days in the ADBR.

The use of PSB for aerobic digestion of the fish sludge led to increasing the PO₄^3-, K, Fe, Zn, Cu, and Mn concentrations compared to the control (<em>p</em> &lt; 0.05).

Moreover, an increase of fish-pathogenic microorganisms can lead to disease outbreaks and mortality making decontamination an essential tool to ensure the cultivation of healthy aquatic organisms under sustainable conditions. Novel approaches, such as cold atmospheric plasma (CAP) and pulsed electric fields (PEF) present promising solutions. Both are effective for water decontamination, scalable to industrial volumes and have the potential of an energy-saving operation. The efficacy was evaluated using RAS water from Baltic sturgeon (<em>Acipenser oxyrinchus</em>). Additionally, to improve the reproducibility of conditions, treatments were compared with model aquaculture water, which was designed from analytical results of RAS water. The study evaluated the inactivation of fish-pathogenic microorganisms by CAP and PEF in comparison to UV. CAP reduced Gram-positive and Gram-negative bacteria by logarithmic reduction factors (log₁₀-RF) of up to 2.1 and 5.9, respectively. A similar inactivation was determined for PEF. Furthermore, a technology efficiency coefficient, putting the required energy in relation to the bacterial inactivation of the respective process, was introduced.

RAS uses filtration to maintain water quality, allowing precise control and reduced water use. RAS offers excellent water control and biosecurity for high-density farming but requires high investment and energy, limiting small-scale use.

In the present study, a novel sterilized thin-film photo-bioreactor (STFPBR) was developed that allows for various trophic modes of microalgal culture. The gas distributor and operational conditions of the STFPBR were optimized accordingly. The results demonstrated that the biomass of <em>C. pyrenoidosa</em> achieved with a coarse sand gas distributor was 42.21 % higher than that obtained using a nano-ceramic gas distributor. The optimal light intensity provided to the STFPBR for microalgae growth was 120 μmol m⁻² s⁻¹, while increasing the light intensity to 160 μmol m⁻² s⁻¹ did not result in any significant difference in biomass concentration. The oxygen content of the air (∼21 %) was sufficient for <em>C. pyrenoidosa</em> growth under mixotrophic conditions. The increased oxygen content in the aeration gas negatively affected microalgae growth. In comparison to photoautotrophic cultivation, utilizing mixotrophic and heterotrophic modes resulted in an over two-fold increase in algal biomass yields. Nevertheless, heterotrophically grown microalgae exhibited the lowest protein content (39.72 %) and chlorophyll concentration (10.24 mg g⁻¹). Conversely, exposure to light during mixotrophic cultivation significantly enhanced both algal protein content (47.87 %) and chlorophyll concentration (16.10 mg g⁻¹).
